March 6, 1929. Serial No. 344,732. I

The present invention relates to heaters, more particularly the air circulating type of heater comprising a stove and a casing surrounding same, of the general type disclosed 5 in my Patent No. 1,695,658, granted Dec. 18,

It has been the general practice to construct a circulating type of heater with an open top so that the greater amount of heat is directed 10 upwardly toward the ceiling of the room in which the heater is located. This has been found to be objectionable on account of the ruination of the wallpaper on the ceiling due to the heat and the depositing of dust, dirt l5 and other foreign matter on the paper.

It is the object of the present invention to provide a novel top construction for the easing or cabinet of an air circulating type of heater which will diffuse and distribute the heated air both upwardly and horizontally, to avoid the objections of the open top type of heater, and to obtain a more efficient distribution of the heat in the room.

A further object is the provision of an air heater casing or cabinet having a corrugated top and outlet apertures or openings so ar ranged as to obtain a desirabledischarge of the heated air.

WVith the foregoing and other objects in view, which will be apparent as the description proceeds, the inventionresides in the construction and arrangementof parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention. is illustrated in the accompanying drawing, wherein- Figure 1 is a plan view of the improved top construction for an air heater.

Fig. 2 is a side elevation thereof, portions being broken away and shown in section.

Fig. 3 is a sectional View on the line 3-3 of Fig. 2.

The top of the casing or jacket which encloses the stove (not shown) may be of sheet metal or may bea casting, and 1s corrugated.

The corrugations may extend from side to side or from front to rear of the casing. As

5 shown, the corrugations are of angular form,

but they may beof sinuous or other suitable shape. i

The corrugations have the upper or outer portions 41, thelo'w'er orinner horizontal portions 5,,and thevertical walls6, forming the mner horizontal "channels 7 ,and the outer, horizontal channels 8. o

The portions & and wallsG are imper'forate, and the portions 4t define thefupper surface or top of the heater having theupwardly. 7

Opening, channels 8. f The portions 5" have apertures 9 therein through which the heated I air nay rise into'and through the channels 8 .The front and rear mus c of the casing or cabinet overlap the walls 6 of the top a't the edges of saidtop,while the side walls, 11 have inturnedflanges 12 at their upper edges 1011 which the ends of the portions 5 are seated. v v

A top frame'18of one or more parts surrounds thetop and the upper ends of the of the inner channels 7, so that the heated air which is encouraged to flowupwardly into the channels 7 .will discharge horizontally from the ends of the channels through the apertures 15. The heated air is thus divided, part flowing upwardly through the apertures 9 and channels 8 towardthe ceiling, and part of the heated air flows from the channels 7 through the apertures, 15.. In this way a diffusion of the heated air is'obtained and a desirable distribution of the heat is accomplished.

Having thus described the invention, what. is claimed as new is: 1. An air heater easing having a corrugated top with outer and inner channels and having apertures for the upward flow of 3. An air heater casing H0 walls, and has an inturnedlip or flange 141 at 4 having a corru- 1'00 7 gated top with inner and outer channels and p a frame surrounding said top, said frame having outlet apertures registering with the ends of the inner channels.

4. An air heater casing having a corrugated top with inner and outer channels and a frame surrounding said top, said frame having outlet apertures registering with the ends of the inner channels, said top having apertures arranged for the upward flow of heated air from within the casing into the outer channels.

5. An air heater casing having a corrugated top with upper and lower portions and walls between them. said u per Portions and walls being imperforate and the lower por tions having apertures.

6. An air heater casing having a corrugated top with upper and lower portions and walls between them, said upper portions and walls being imperforate and the lower portions having apertures, the casing having provision for the discharge of air from the ends of the inner channels defined by said upper portions and walls.

7. An air heater casing having a corrugated top and a top frame surrounding same, said top having upper and lower portions and walls between them, said upper portions and walls being imperforate and the lower portions having apertures, said frame having outlet apertures registering with the ends of the inner channels defined by said upper portions and walls.

In testimony whereof I hereunto aifix my signature. 7
